Abstract (en)
[origin: EP3235658A1] CONSTRUCTIVE ARRANGEMENT OF A FLEXIBLE WHEEL FOR WHEELBARROW OR MANUALLY TRACTIONED INDUSTRIAL CARTS is constituted by a single block that comprehends three parts: the outer ring(1), the center wall(2), and the inner ring(3); and the outer ring(1) has on its extremity a tread surface(15), and as tangents on each side it has side tread surfaces(12); and each side tread surface(12) has a plurality of radial cavities(11) spaced along the wheel; and the radial cavities(11) of a side tread surface(12) are not aligned in relation to the radial cavities(11a) of the opposite side tread surface(12a); and the center wall(2) is a flat, solid, ring-shaped wall contained in the central plane which contains the body of the wheel, and on each side of the flat wall there are a plurality of flexible structures(14) radially aligned to the radial cavities(11) contained in the outer ring(1); and the inner ring(3) is constituted of a circular wall(31), a reinforcement rim(32), and mass reducers(33); and the mass reducers(33) are recesses with radial walls.
